DUMP GAR Application filed November 1,1927.

This invention in general relates to dump cars of t he type in which pneumatically actuated mechanisms are causedtoi operate selectively so as to permit the car body to is to be effected.

More particularly, this invention aims to provide a dump cai of simple construction and one which is extremely strong and durable in operation.

One object of the invention is to provide a car of the character specified which will operate to dump a load with a minimum of pneumatic pressure.

Another object of the present invention is to provide a dump car having a simplied form of body support in which rocking or wearing strains originating in the carbody when in normal position arel transferred to the underframe through rugged underframe parts.

VAnother object of the invention is the provision of a simplified form Vof body supporting and locking mechanism in which rocking or wearing strains originating in the car b position ody while in its normal righted are transferred directly to the stra-ins, and which parts do not interfere with the usual bolsteil constructions.

Other objects and advantagesof this invention will be apparent from the following descriptio n taken in conjunction with the accompanying drawings in which:

Referring now more particularly to the drawings, a car` underframe is indicated generally at 2 and a car bodyy at 4:, the latter being mounted for lateral .dumpingy movement on the underframe 2.

VReferring specifically to the underframe 2, there is shown a center sill or girder 6 formed of the spaced sillsr 8 and a top plate 10. The sills 8 areprovided with aline'd openings 11 and a supporting spacer 13 securedto said sills adjacent the openings by suitable means such as rivets or the like.

At `opposite ends of the center girder 6 'and adjacent the ends of the car body are end constructions designated generally in Fig. 2 as14 of which only one is shown, it being understood that the end constructions are identicaland that a particular description' of one suffices forboth. As shown more clearly in Figs 3, '1l` and 5, the end structure 14 includes relatively wide supporting plates `1 6 secured to the lower outturned flanges 18 Y are provided with a diaphragm portion 22 flanged at 24 to connect with a downwardly projected portion 26 of the supporting plate, and the end of this projected portion is received between the flange 28 of the sills 8 and an outwardly extended flange 30 of a tie casting 12, and said projected portion and flanges 28 and 30 are riveted or otherwise secured together to form a rugged uni-k tary structure. The parts of the end construction 14 are identical on each side of the central girder, and a description of one suffices for both. y

Secured to the plates 20 are trackways each formed of a pair of angles 30, the trackways extending toward the `center girder 6 to a point adjacent the latter and accommodating bearing blocks comprising the vrollers 32 which are connected by axles 34; each bearing block supporting the lower elongated bifurcated end 36 of ai strut element 38. The strut element 38 extends upwardly and a portion 40 thereof is provided with an opening through which extends a piston rod hereinafter described, and the extreme end is formed into an open socket 44 having on its upper end a push finger 45.

As will be clearly pointed out hereafter,

the strut of which element 38 is a part supports the car body and is formed of upper and lower sections 38 and 112; element 38 being the lower section. From an inspection of Fig. 4 it can be seen that two struts are provided at the end of the car, but adew script-ion ofV one suflices for both.

The spaced web plates 20 are provided with a cover plate 46 which extends across the center sill as clearly shown in Fig. 4, and said cover plate is provided with suitable openings through'` which extend valve casings 48 having valves 50 therein,said'valve casings being secured to and connecting a cylinder hereafter described. As particularly shown in Fig. 4, the cover plate 46 is relatively short and is slotted for a portion of its length as indicated at 46 and each of the plates 20 has secured to the upper flange thereof an inwardly extending plate 54, the inner edges of the plates 54 defining a. slot 56 which permits lateral movement of the strut element 38 as described hereafter in the operation of the device, A splice bar 58 is provided for reinforcing purposes, the same being secured to the plates 46 and 54 across the meeting edges thereof. The construction of the cover plate and the. cooperating plates 54, as shown in the draw ings, is merely by way of example,as obviously, the cover plates may extend the full length of the web'plates 20 and across the center sill and have a slotk formed in each end thereof within the spirit of the invention.

Mounted on the plate 46 and secured thereto by rivets or the like extending through integral flanges 60, is an air cylinder 62 to which the valve casings 48, heretofore mentioned, are secured. lVithin this cylinder 62 is a reciproca-ting piston 66 having a piston rod 68 (heretofore mentioned) extending therethrough and through the opposite ends of the cylinder. Thev cxtreme ends of the piston rod 68 extend through the beforementioned openings in the strut element 38 .and are connected to the latter by means of a pin 72 extending through a casting 70 formed on the strut elements.

A valve rod 74 is provided which extends through the openings in the side plates 8 and its opposite ends are extended through the opposite carriages 36; the two carriages being connected 'to said rod 74 by nuts 76. Substantially midway of the ends of this valve rod 74 is a valve operator 78 which, in

the instance shown, is an enlargement or cam so arranged as to be normally positioned betweenthe valves 50 when the car body is in the position illustrated in Fig. 4 but which is adapted to contact with said valves 50 upon movement of the valve rod 74. Communicating with each end of the cylinder 62 is an air line as indicated at 80 and 82.

Referring now to Fig. 5, the cylinder 62 is provided with upwardly extending spaced flanges 84 which define between them an elongated socket within which is secured 'by rivets or the like a guide 86, which, in the instance shown more clearly in` this figure, is formed of front and back plates 88 and. 90 respectively and bottom and top plates 89 and 91, respectively. The front and back plates 88 and 90 are each provided with a slot 92'formed therein and a marginal flange 94 is formed around the edge of each slot to provide a bearing surface for a guide pin 96 carried by the reinforced guide casting 98 secured to the end 100 of the car body. The guide casting 98 may be, and preferably is, provided with oppositely arranged bearings 102 for the guide pin. The parts just described are received within a housing, formed by the end of the car body and a spaced diaphragm 104 connected to the end 100 by a channel 106 extending down both sides of the car and across the top thereof, said channel defining a top and side portions for the end construction and housing. A suitable reinforcing spacer plate 108 is. also provided intermediate the ends kof the housing secured to the end 100 and the plate 104. i

Connecting the strut elements 38 at points 111 belowthe sockets 44 is a tie or tension rod formed of connected sections and 110. As clearly shown in Fig. 13, the adacent ends of sections 110 and 110 lap each v tact-s with the ends of the slots, continued shifting of the rodsactuating the car body to dumping position as will be obvious. The tension rods, as will be apparent, serve as rocking links acting under tension to actuate the body to dumping position and also toward normal righted position. Y

The sockets 44 each removablyT mount the lower end of a bell crank or lock arm112 pivotally secured to a casting 113 secured to the car body, and the short arm of said crank is formed into a latch 114 which engages within the latch keeper 116 formed on a side gate 118 hingedly connected at 119 to the car body. When the parts arefin the position illustrated in Fig. 4,`it will be apparent that the strut elements 38 and'tlieir associated lower bell crank arms serve to support and retain the car body in its normal position without the employment of other agencies such as shackle chains or hooks. Suitable openings 119 are provided in the housing for receiving the keeper when the gate is in closed position. The gate v118 carries a reinforcing Arib 120, and t-lie loweiI end of this rib is formed into an angle 122 having an inwardly directed socket 124 which pivotally secures one end of an operating lever 126. The other end of lever 126 is connected with a socket 128 formed on the upright extension 130 of a bracket132 secured to the top plate of the center sill. ln practice, it has been found satisfactory to form the bracket of two sections and in Fig. 5 an inverted T 134 is shown, the same being riveted to the top plate 10 and the extensions 130 are preferably cast to the form shown in said Fig. 5 providing a lower slotted piece 136 which is secured to the leg of the T by suitable means such as rivets or the like.

It has been found necessary to form the lever 126 of telescopic sections to compensate for certain play in the several parts during the dumping operation, and to that end each `lever 126 is formed of telescoping sections 138 and 140 respectively (see Fig. 7) and when vsaid sections are fully telescoped, the end of socket 124 will abut the end of section 140.

Referring now to Figs. 2, 5 and 6, in which are shown the car bodydetails, 142 indicates the floor of the car, the same being supported by space-d Z-bars 144V arranged` transversely of the body and riveted to a substantially U-shaped sill 146 extending longitudinally of the car body and immediately over the center sill or girder 6. The sill 146 is more clearly illustratedin Fig, 6,

and' comprises opposed Z-bars 148 having corresponding their upper legs riveted to the Z-bars: 144; the bars 148 being Vso placed as to provide a substantial space between the webs thereof Vwithin whichisfsecured a brace 150 riveted or otherwise secured to the .bars 148 and to the bars 144. I y

A truss-152 is provided adjacenteach floor beam, said trusses each` being connected at each end thereof to the ends of veach Z-bar 144, the trusses 152extending beneath the projections or knobs 158 which are adapted 'to engage within complementary depressions 160 formed in a rackplate 162 secured. to the center girder 6, the latter being provided withv marginally flanged supporting .web

castings 164 secured thereto and provided with retaining shoulders 166 serving as stops for limiting the movement of the body. 'As

shown` more clearly in Fig. 5, the `rocker 156 .-3

is substantially ahollow casting having a base 168, on which the knobs 158 are formed. This base is mounted for movement on the rackplate 162, as before-mentioned, and

angles 170 secured to the plate 162 deinef between them the channel in which the rocker 156 moves. .The construction just described, it is obvious, provides, in effect, a `rack and pinion mounting to permit rocking movement of the car body.r At this point, A'

it is desirabley to -call attention tothe speciiic mounting of the car body for rocking and are substantially of arcuate shape# The T30 Y edges of these rockers are each formedwith movement, in connection with the particuf lai' ooeratin(T means therefor and referring b 7 t) again to Figs..4 and 7, which have previous-f` 'ly been described, it can be seen 'that when fluid pressure .is admitted to theleft hand portion ofthe cylinder, the car vbody will be moved toward the right, the guide-pin 96 moving inthe slot 92 while at the same time the'body will rock on the rockers 156 in an arc, the center of which is much `below the bottom ofthe car body.w 'y y Referring iiow to Figs. 9, 10 and 11,

wherein is shown a modiiiedform of the invention, it can be seen that the fundamental or underlying inventive concept of the other figures of the drawings is -maintained here,

the car comprising the `center sill 172, 'theY endconstruction 174, the operating cylinder 176, tlieside gates 178 together with the operating levers 180 therefor, all similar to the parts shown in Figs. 1 Ato 8, inclusive; Y

` The car shown in Figs; 9 to 11, however,l

`ly closed by a gate 186 pivotally mounted at 188 (see Fig. 11), withina discharge outlet casing indicated generally at 190 and formed preferably of spaced Z-bars 191 and 193 riveted or otherwise secured to the car bottom 182 adjacent the openings 184 therein. As shown distinctly in Fig. 11, each gate 186 is vprovided with a depending cam face 192 which is in contact with a 'roller 194 carried by ahorizontal'ly moving retaining element 196 which in the instance shown is a rod. 1fA desired, the roller 194 may be omitted and the cam face may act directly on the rod 196 within the spirit ofthe invention.

The sides of the car have secured thereto yat the car bottom, an angle 198 to which are connected the cross-beams 200, this construction being similar to the construction disclosed in the car in Figs. 1 to 8, inclusive. Secured to the lower flanges of the crossbeams 200 and extending longitudinally of the car body are spaced Z-barsv 201 and 203 respectively, which also extend through suitable openings provided in the rockers 205 (similar to the rockers shown in Figs. 1 to 8, inclusive), and extending between and connected to each of these Z-bars 201 and 203 by means of rivets 205 or the like, are webs 207 each provided with a horizontally arranged slot 209, within which slots the rod 194 isadapted to move.

Extending longitudinally ofthe car and mounted foi` rotation in the before-mentioned cross-beams 200 is an operating arm `202 to which are secured one end of flexible connectors 204, one for eachof the gates 186, and the other end of each of these connectors 204 is connected to the retaining rod 196. One end of the operating arm 202 carries a lever 206 cooperating with suitable ratchet means 208 to retain the lever and its associated operating arm '202 in predetermined positions in a manner well understood. It will lbe apparent that upon Vrotation of the arm 202 in one direction, connectors 204 will be loosened thereby permitting the gates 186 to swing downwardly on their pivots and thus permit the lading in the car body to be discharged through the openings 186. A reversal of rotation of the rod 202 will draw the operating arm 196 toward the left, see Fig. 11, and the rollers 194 on the operating arm by engagement with the cam faces 192 will force the gates 186 to closed position.

Figure 12 shows a modification of the roller structure shown at 20 and 32 in Figs. 3 and 5; and it can be seen that a U-shaped support 210 is secured to the plate 16, said support mounting opposed castings 212 provided with attaching flanges 214 by which said castings are secured to the plate 54. The castings 212 are each formed wit-h diverging guides or trackways 216 within which are mounted for movement the frustoconical rollers or wheels 218 connected by the gates.

axle 34; this construction affording substantially complete protection for the rollers from dirt or other foreign matter. y

lIn the operation of the vpresent invention with the parts thereof in the position illustrated in Fig. 4, the car body is retained in its upright position by means of the strut elements 38 with the cooperating lower ends of the angles 112 and it will be apparent that the car body is securely retained in such position due to the engagement of the latches 114 with their cooperating keepers.

1t will further beapparent that the car body is also retained in the position illustrated in said Fig. 4 by means of the levers 126 andthe side gates 118. When it is desired to dump the car, fluid under pressure is admitted to either side of the piston 66 within the cylinder 62, depending upon the side on which the tilting is to be effected and forythe purposes of this case, we will consider Fig. 7. To dump the car to the right as shown in said Fig. 7, vthe fluid under pressure is admitted through the air-line into the -adjacent portion of theV cylinder, and such fluid will move the piston 66 to the right such movement carrying the strut element` 38 to the right breaking the bearing and locking joint at the socket 44 of the strut element, the finger 45 urging the lower end of the angle 112 in an outward direction until the latch 114 is released from its engagement with its keeper 116 whereupon the side gate 118 will swing on its hinge 119. After the latch 114 has been released, continued movement of the strut will cause rod 110 to act against pin 96 to force Ythe body to be carried to the right, the guide pin 96 working in the slot 92 on the bearing flanges thereof until said pin reaches substantially the end of said slot, and during this movement, the car body will rock due to the engagement of the rocker plate 156 with its rack plate 162 until the body assumes the position shown in dot and dash lines in Fig. 7, whereupon the lading in the car will be discharged through the openings in the sides thereof formed by the swinging of the end The lost motion connection of the links 110 and 110 with pin 96 is such as to permit movement of the strut and links relative to the body to an amount suliicient to release the latch prior to commencement of the dumping movement of the body.

During the movement of the piston 66 as a result of fluid pressure exerted thereagainst, thevalve rod 74 due to its connection with the carriage at the lower end of the strut element 38 will be moved correspondingly, and thesurface 78 of said valve rod will engage the adjacent valve 50 and open a discharge through the valve casing from Vthe cylinder on the opposite side of the Vpiston 66 to exhaust air in said cylinderI portion in advance of the approaching piston 66. lVhen the surface 78 has completely passed the valve against Which it 1s operated, the valve 5()V will be receded and thus close any outlet trom the cylinder to the atmosphere therethrough and the remaining air in that portion ot' the cylinder will be exhausted through the air line 82 in advance or" the approaching piston 66.

After the lading in the car has been dumped, to replace the bodyjto' the `position shown in Fig. 4, the fluid nuclei' pressure is then passed into the right-hand yportion of the cylinder 62 through the air line 82, urging the piston G6 back to its normalfposition, and the reverse of the operationjust described will occur; inV other words, the piston will be forced to the Vleft until the surface 'T8 of its associated valve rod 74 engages the adjacent valve 50' whereby to open a discharge from the cylinder through the valve casing of said valve which will permit the exhaust of fluid under pressure directed to the atmosphere and prevent the Jfurther traveling of the piston 66 by reducing the pressure exerted thereagainst. j Prior to the complete positioning of the car body, itis apparent that the weight of said bod-y Will be suicient to cause the latter to drop by gravity to the position shown in said Fig. 4 and the lower ends of the angles 112 will assume their position Within the sockets the cai` thus being normally'positioned.
